It is neither necessary nor desirable to attempt the formulation of a single, specific
definition of what constitutes the practice of law. Functionally, the practice of law
relates to the rendition of services for others that call for the professional judgment of
a lawyer. The essence of the professional judgment of the lawyer is his educated ability
to relate the general body and philosophy of law to a specific legal problem of a client;
and thus, the public interest will be better served if only lawyers are permitted to act
in matters involving professional judgment. Where this professional judgment is not
involved, non-lawyers, such as court clerks, police officers, abstracters, and many
governmental employees, may engage in occupations that require a special knowledge of law
in certain areas. But the services of a lawyer are essential in the public interest
whenever the exercise of professional legal judgment is required.
